process the need to stop, apply the brakes, and come to a complete stop.
-Reaction distance - -The distance the fire apparatus ravels after you
recognize the hazard, remove your foot from the accelerator, and apply the
brakes.

-Ungaurded railroad crossing - -Come to a complete stop, turn off sirens and
roll down windows; operate apparatus on idle, and listen for the sound of an
oncoming train
-Intersections with railroad crossbars - -Never proceed between the
crossbars in an attempt to continue the response
-Fuel guage - -Fuel tanks should never drop below the halfway level
-Voltmeter - -Measures the voltage across the battery terminals and gives
an indication of the electrical condition of the battery
-Air brake test - -Turn apparatus on, allow air compressor to build up to 110
PSI, shut off engine but leave battery in on position, step on and off brake
pedal. An audible alarm should signal before pressure drops to less than 60
PSI.
-Confined space turnaround maneuver - -Establish a 50x12 ft lane; driver
enters area and turns the apparatus 180 degrees and leaves area
-Vaccuum test before - -Before: remove all discharge caps and drain
booster tank; chock wheels
-Vacuum test during - -During: drain water from fire pump and booster
tank; close all drains, intake valves, cooler lines, and any other sources of
vacuum leaks to isolate fire pump; place caps on all suction or external

-Vacuum test during cont (1) - -Turn battery on (not necessary to start
engine); fully open primer control handle and hold in that position
, -Vacuum test during cont (2) - -Continue to hold hand in fully engaged
position until max vacuum is achieved (15-20 seconds); You should see a
vacuum reading of approx 22in HG on supply master gauge. Return handle
to fully closed position.
-Vacuum test after - -Record reading and wait 5 minutes and record again;
reading should not drop below more than 10in Hg in 5 minutes. If it does
follow SOPs and have vacuum leak repaired

pressure difference tread depth, ________ of the tires carries too much of the

-One
-Function of maintenance records: - -To find any abnormalities so corrective
action can be taken
-Overthrottling can result in: - -Lugging; Lugging occurs when the throttle is
applied while the transmission is too high a gear for a given set of conditions
-When over throttling a Diesel engine, more fuel is being injected than can
be burned which causes: - -Excessive amount of carbon particles issuing
from the exhaust (black smoke) oil dilution, and additional fuel consumption

- -Weight of the apparatus
Condition of the brakes
Tires
Road surface
-Factors that influence a drivers ability to stop the vehicle: - -Condition and
slope of the driving surface
Speed being traveled
Weight of the vehicle
Type and condition of the vehicles braking system

conditions
Failure to appreciate the proper weight shifts for heavy apparatus
Failing to anticipate obstacles
Improper use of auxiliary braking devices
